x86: correct size for stack bound check for privileged stack

Browse source 
Previous commit changed the privileged stack size to be using
kconfig CONFIG_PRIVILEGED_STACK_SIZE instead of simply
CONFIG_MMU_PAGE_SIZE. However, the stack bound check function
was still using the MMU page size, so fix that.
